About the Program
Nutrition plays a vital role in maintaining health and in the prevention and treatment of diseases. Registered Dietitian Nutritionists (RDN)s are the food and nutrition experts who translate the science of nutrition into personalized recommendations to help people prevent and manage medical conditions, such as diabetes, cancer, heart disease, and many more. To become a RDN, students must complete required coursework as well as a 1000 hour supervised practice experience, both from accredited dietetics programs. Required courses include biology, chemistry, biochemistry, medical nutrition therapy, nutrition assessment, diet selection and planning, and food service systems management.
At Purdue, students complete all required coursework for dietetics in the Didactic Program in Nutrition and Dietetics (DPD), and then apply to either an outside dietetics internship or the Coordinated Program in Dietetics at Purdue to complete the required accredited supervised practice. Upon completion of supervised practice, students are eligible to sit for the national registration examination for dietitians.
Effective January 1, 2024, the Commission on Dietetic Registration (CDR) will require a minimum of a master’s degree to be eligible to take the credentialing exam to become a registered dietitian nutritionist (RDN). The undergraduate Coordinated Program in Dietetics will be retired following the 2022-2023 academic year and is expected to be replaced by a graduate-level experiential program to fulfill the requirements for a graduate degree and 1000 hours of supervised practice experience.
With a focus on preventive health and nutrition, Dietetics is an excellent pre-professional major. More information about the DPD.
